The position of splenium 67.
[the phase state of cold-producing medium]
Fig. 6 is the figure of the state schematically showing the cold-producing medium within radiator.To the first radiator 50 (region ac),
The refrigerant condition of second radiator 51 and the 3rd radiator 52 (region cd), condensation suppressor 53 (region df) inside is said
Bright.Each position in kind of refrigeration cycle shown in labelling a～f and Fig. 5 shown in Fig. 6 is corresponding, and labelling a represents compressor 24
Discharge side, labelling b represents that cold-producing medium is changed into the point in gas-liquid two-phase region from vapor phase areas, and labelling c represents the first radiator 50
And between the second radiator 51, labelling d represents one end of condensation suppressor 53, and labelling e represents that cold-producing medium is from gas-liquid two-phase region
Being changed into the point of liquid phase region, labelling f represents the other end of condensation suppressor 53.Labelling d, f the most also illustrate.Herein,
The situation that from the d side, one end of condensation suppressor 53, cold-producing medium is flow to other end f side illustrates.
Compress through compressor 24 and become the cold-producing medium of High Temperature High Pressure and be in the vapor phase areas being made up of gas phase composition 71.Adjust
Whole piping length and/or the rotating speed etc. of mechanic chamber fan 54 so that cold-producing medium is incited somebody to action by the first to the 3rd radiator 50～52
Heat is discharged into outside storehouse, and before arriving one end d of condensation suppressor 53, is changed to by gas phase composition 71 and liquid phase ingredient
The state that among gas-liquid two-phase region that 72 are obtained by mixing and the liquid phase region that is made up of liquid phase ingredient 72, enthalpy is bigger.From effectively
From the viewpoint of suppression condensation, at one end d of condensation suppressor 53, the cold-producing medium of flowing is preferably gas-liquid two-phase region.And
And, preferably it is adjusted so that the cold-producing medium of flowing is liquid phase region at the other end f of condensation suppressor 53.Carry out herein
Adjust, so that being vapor phase areas before the midway of the first radiator 50 (region ab), from the midway of the first radiator 50 to knot
The midway (region be) of dew suppressor 53 is gas-liquid two-phase region, from the midway of condensation suppressor 53 to the other end (region ef) is
Liquid phase region.Therefore, in the cold-producing medium stream of Fig. 5, the temperature of the end 53f of the outflow side of condensation suppressor 53 is used for flowing into
The end 53d of side is low.
Flow channel switching valve 48, by switching the first state and the second state as described later, changes cold-producing medium at pipe
57, condensation suppressor 53 and pipe 58 in flowing order.I.e., in the first state, cold-producing medium is according to pipe 57, condensation suppressor
53, the sequential flowing of pipe 58, and flow to other end f from one end d in condensation suppressor 53.And in the second condition, press
Look after 58, condense suppressor 53, the sequential flowing of pipe 57, and flows to one end d from other end f in condensation suppressor 53.
Herein, it is possible to make from opening 75 to the piping length of opening 77, i.e. pipe 57, condensation suppressor 53 and the pipe arrangement of pipe 58
The lower limit of length is for example, from discharge side end (Fig. 5 in place of labelling a) the joining to relief portion 67 upstream side of compressor 24
The 10% of length of tube, 15%, 20%, 25%.If increasing this piping length, then cold-producing medium mistake of flowing in condensation suppressor 53
Gradually becoming low temperature in journey, what flowed in the downstream of condensation suppressor 53 becomes the temperature cold-producing medium than relatively low liquid phase region,
It is possible to suppression invades the hot intrusion volume in storehouse.On the other hand, pipe 57, condensation suppressor 53 and the piping length of pipe 58
Higher limit can be such as from the discharge side end of compressor 24 to relief portion 67 upstream side the 50% of piping length, 40%,
30%.If shortening this piping length, then the upstream side of condensation suppressor 53 is by such as gas-liquid two-phase region or upstream, liquid phase region
The refrigerant heat that the temperature of side is higher, it is possible to effectively suppress condensation.That is, the upstream side of condensation suppressor 53 becomes easy
Heating is it is thus possible to effectively suppress condensation, and downstream then suppresses heating it is thus possible to suppress hot intrusion volume.
It addition, can make the lower limit of the piping length of condensation suppressor 53 is such as pipe 57, condensation suppressor 53 and pipe
The 50% of the piping length of 58,65%, 80%.If increasing the piping length of condensation suppressor 53, then condensation suppressor 53 is upper
The cold-producing medium of the liquid phase region higher for gas-liquid two-phase region or temperature that trip effluent is dynamic, and downstream flowing for temperature ratio
The cold-producing medium of relatively low liquid phase region, is readily available the effect above.Further, due to downstream that is first shape of the suppressor 53 that condenses
In the pipe 57 under pipe the 58, second state under state, flowing is the liquid phase refrigerant that density is higher, so by making pipe 57, pipe 58
Shorter, it is suppressed that the refrigerant amount enclosed in kind of refrigeration cycle.Now, pipe 57 and the respective piping length of pipe 58 both can substantially phases
Together can also be different, but from the viewpoint of the symmetry when the switching improving aftermentioned first state and the second state, the most greatly
Cause identical.Set piping length as described above, under any state of the first state described later and the second state, due to
The cold-producing medium of the liquid phase region higher for gas-liquid two-phase region or temperature of the upstream side flowing of condensation suppressor 53, and downstream
Effluent dynamic for temperature than the cold-producing medium of relatively low liquid phase region, therefore, it is possible to increase one end and the other end of condensation suppressor 53
